Well you sir, are different than most of the long time Tomb Raider fans I know. They all seem to hate from The Angel of Darkness forward because they don't "feel like" the PS1 games, particularly due to the fact that there's no actual tomb raiding going on.
That's not to say that there aren't plenty of legitimate reasons to hate The Angel of Darkness, which I still believe delivered a mighty blow to the franchise in terms of cultural significance.
I also don't know what you mean when you say Underworld was behind the times. Care to elaborate?
